What breaker do I need? Q2020 or Q2020NC?
I am putting in a new circuit in my workshop (bought a 12a shopvac and it
makes the lights flicker) so I need to replace a full size 20a breaker in my Sylvania box with two half size breakers. I went to HD and they had two of them, a non-current limiting breaker for $15 and another one for $10. I asked the clerk what the difference was; he said there wasn't any difference and told me to buy the cheaper one. That didn't make any sense so I asked a guy in the aisle if he knew. He didn't but after looking at them pointed out that cheap one has a little contact and the expensive one had a big contact. He said the expensive one can be used in all boxes, but the cheap one can be used in all boxes. That makes a lot more sense, but still doesn't explain what non-current limiting means. So, does anyone know what the difference is, and which I should use. Funny think is I have put in two others without encountering this issue before. I wonder if I used the right ones??! |
